United States Patent O 3,046,976 VENTED WALL FLUE Robert E. Aggscn,Azalea, Greg. (5322 McKenzie Highway, Springfield, Greg), assigner fforty-nine percent to Eddie E. Parker, Glendale, Oreg.

Filed June 26, 1956, Ser. No. 593,953 4 Claims. (Cl. 126-316) Thisinvention relates in general to new and usefull improvements in flueconstruction, and more specifically to a vent wall flue.

In ordinary iiu'e construction access to the interior of a chimneywithin a room is obtained by placing in the wall of the room and thewall of the chimney a flue liner. The stove or furnace is then connectedto the chimney by terminating `a stove pipe in the flue liner. lIn manyinstances the iiue liner does not have a proper seal with respect to thechimney so that gases will 'escape between the flue liner and thechimney. Also, it is difficult to obtain the proper seal between themetal smoke pipe and the ceramic flue liner, ceramic material generallybeing used for the formation of flues. Another problem has been thatlittle provision has been made for the overheating of the smoke pipe`and the subsequent overheating of the wall structure so that iires areoften caused by overheated smoke pipes.

It is therefore the primary object of this invention to provide a wallflue which is vented whereby the wall in the vicinity of the flue is notsubject to overheating thereby preventing fires due to overheated smokepipes.

Another object of this invention is to provide an irnproved wall uewhich is formed of metallic materials and which is formed in sectionswhereby shifting of the chimney With respect to the wall of the buildingwill not result in the cracking of the various components of the wall ueso as to permit the escape of gases and the like.

Another object of this invention is to provide animproved wall fluewhich is so constructed whereby a smoke pipe may be passed entirelytherethrough with the smoke pipe having its inner end disposed withinthe confines of the chimney thus permitting an elective seal between thechimney 'and the smoke pipe.

A further object of this invention is to provide an improved wall flueconstruction which is adjustable whereby the wall illue may be adjustedto walls of various thicknesses.

Still further object of this invention is to provide an improved wallflue of the vented type, the venting of the wall flue being of such anature whereby radiated heat from `a smoke pipe passing lthrough theWall iiue, is

l circulated back into the room in the wall of which the wall ue ismounted.

These together with other objects and advantages which will becomesubsequently apparent reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the laccompanying ldrawings forming a part hereof, whereinlike numerals refer to like parts throughout, and in which:

FIGURE l is a vertical sectional view taken through an intermediateportion of a chimney and adjoining wall of .a room and shows the generalrelationship of the wall flue whichis the subject of Athis inventionwith respect to both the chimney and a smoke pipe passing therethrough;

FIGURE 2 is a fragmentary horizontal sectional View taken through thechimney and the wall in the vicinity of the wall flue and shows furtherthe general relationship between the wall flue, the smoke pipe and thechimney;

FIGURE 3 is an enlarged fragmentary sectional view taken substantiallyupon the plane indicated by the section line 3 3 of FIGURE 1 and showsthe general appearance of the front cover plate of the Wall ilue;

ICC

FIGURE 4 is an enlarged fragmentary horizontal sectional view takensubstantial-ly upon the plane indicated by the section line 4-'4 ofFIGURE l, only the wall flue and the smoke pipe being shown, thespecific Idetails of the wall ue and the connection of the smoke piperelative thereto being clearly illustrated;

FIGURE 5 is an enlarged fragmentary sectional View taken substantiallyupon the plane indicated by the section line 5 5 `of FIGURE 2, the Viewbeing taken only through the wall ilue and the smoke pipe and shows theflow of air through the Wall flue; and

FIGURE 6 is an enlarged sectional view taken substantially upon theplane indicated by the section line 66 of FIGURE 5 and shows the mannerin which a smoke pipe is supported within the wall flue.

Referring now to the drawings in detail, it will be seen that there isillustrated in FIGURES l and 2 a conventional stove chimney arrangementwhich includes a stove 10 having a smoke pipe 12 connected thereto.G-ases from the smoke pipe 12 exit into a chimney 14 having a draftpassage 16 extending vertically therethrough. Extending through a wallof the chimney 14 and opening into the draft passage 16 is an opening18.

Disposed intermediate the stove 10 and the chimney 14 is a Wall which isreferred to in general by the reference numeral 20. The Wall 20 includesa plurality of studs 22 which have secured to the faces thereof remotefrom the chimney 14 a wall forming material 24. Normally there would bemounted within the opening 18 and carried by the wall 20 a ceramic flueliner which would be sealed with respect to the chimney 14. The smokepipe 12 would enter into the room end of the flue liner (not shown) andterminate short of the chimney 14. This would permit leakage of gasesbetween the ue liner and the chimney 14. Also, the ue liner is normallysupported by the studs 22 or other parts of the wall 2b and Whensubjected to overheating could possibly cause a re.

Mounted within the wall 2t) and extending between the chimney 14 throughthe opening 18 is the vented wall iiue which is the subject of thisinvention, the Wall ue being referred to in general by the referencenumeral 26. The wall flue 26, `as is best illustrated in FIGURES 4 and5, includes an inner sleeve 28 which is preferably circular in crosssection. Disposed about that portion of the inner sleeve 28 remote fromthe chinmey 14 is an outer sleeve which is referred to in general by thereference numeral 30. The outer -sleeve 30, as is best illustrated inFIGURE 6, is preferably square in cross-section. The outer sleeve 30 isformed in sections and includes an inner section 32 which is telescopedover the inner end of an outer section 34. By Iadjusting the sections 32and 34 relative to each other, the outer sleeve 3i) maybe adjusted toaccommodate walls of various thicknesses.

The inner sleeve 28 is connected to the outer sleeve 36 by means of afront cover plate 36 which is generally square in outline, as is bestillustrated in FIGURE 3. Front cover plate 3'6 terminates along its sideedges in vertically side flanges 33 which `are secured by means offasteners 40 in fa'ce-to-face engagement with vertical flanges 42extending upwardly a-long the outer edges of the outer section 34. Thefront cover plate 36 is provided with a central opening `44 of -a sizeto snugly receive the outer end of the inner sleeve 28. If dired, theinner sleeve 28 may beI suitably secured by welding or the like to thefront cover plate 36.

The inner section 32 of the outer sleeve 30 terminates in an end wall 46which in turn has an `opening 48 therethrough bounded by a peripheralflange Sil. The opening 48 is of a size to snugly receive the innersleeve 2S and outlet opening 62.

Y the l'lange 50 Aforms a suitable support for the inner sleeve 28.

The outer section 34 of the outer sleeve 36 includes a lower dependingange 52 which is disposed in the same plane as the flanges 42. Thei'lange 52 extends down below the lower edge of Ithe front cover plate36 and terminates in a forward and downwardly sloping lip 54.

The outer section 34 also includes an upper ilanger which is disposedcoplanar with the flange 52. The flange 56 extends upwardly above theupper edge of the front cover plate 36 and terminates in an upwardly andor- Wardly directed lip `S. It is to be noted that the cover plate 36 isspaced from the lips 54 and 5S thus providing a lower inlet opening edand an upper outlet opening 62.

In order that air will not pass directly upwardly about the inner sleeve2S 'from the inlet opening 60 to the outlet opening 62 immediatelybehind the front cover Vplate 36, there is positioned within the outersleeve 30 and about the inner sleeve bale 64. The baille 64 is carriedbythe `front cover plate 36 Iand is secured to the lower part thereof bysuitable fastener 66. The baille 64 is cut to receive the inner sleeve28 thus causing the ow of air therearound.

In order that a limited quantity of air may also be cirv Voulated withinthe inner sleeve 2S, the inner sleeve 2'8 is provided with suitableopenings 68. These openings 68 are best illustrated in FIGURES 5 and 6.

In order that the inner sleeve 28 may properly support the smoke pipe12, the extreme end of the inner sleeve 28 terminates in a reduced neckportion '70. The reduced neck portion 70 is intended to becomeinterlockingly engaged with the inner end of the smoke pipe 12 as at 72.Also, Ithe outer `part of the inner sleeve 2S is provided with suitablespacing ribs 74 for engaging an intermediate part of the smoke pipe 12,as is best illustrated in FIGURE 6.

In the proper mounting of the vented wall iiue 26,

the inner sleeve 2S will `beof a length so as to pass into the interiorof the chimney 14, as is best illustrated in FIGURES l and 2. The outersleeve 30 will be `adjusted to ybe of proper length, as is bestillustrated in FIGURES 1 and 2 according to the wall thickness. Thesmoke pipe 12 will be of a length to pass entirely through the innersleeve 23 and have in relationship with respect thereto as is bestillustrated in FIGURES 4 and 5. Thus, the smoke pipe 12 will terminatewithin the chimney 14 and the escape of gases intermediate the end ofthe smoke pipe 12 and lthe chimney 14 will be prevented.

Due to convection, relative cool air will enter into the air inlet 6i)and will pass upwardly through the wall ue .26. A majority of the airwill pass around the inner Ysleeve 28 and between the inner sleeve 28and the outer l sleeve 30 so as' to maintain a cool air space betweenthe two. A certain amount of the air will pass into the interior of theinner sleeve 28 and around the smoke pipe 12 so as to reduce thetemperature of the smoke pipe 12. This air will exit through .the upperpartof the inner sleeve 2S into the outer sleeve Sil and out through the'Ihus it will be readily apparent that the ilue 26 is suliciently ventedso as to prevent overheating. Also, by venting the tlue 26 and removingyfrom Athe smoke pipe 12 a certain amount of the waste heat carriedthereby, it will be seen that additional heat is provided yfor the roomin which the stove 10 is mounted. This will provide a suitable saving.

While the Wall tine has been specifically illustrated `and describedwith respect .to an interior wall, it will be readily apparent that theinvention is not intended to ,principles of the invention. `Further,since numerous engagement in a chimney opening and an outer sleeve Y forengagement in a wall opening registered with said chimney opening,connecting means mounting said inner sleeve in spaced nested relationWithin said outer sleeve, spacing means carried by said inner sleeve forretaining a smoke pipe in spaced nested relation within said innersleeve, one end portion or" said outer sleeve adapted to projectoutwardly of a wall openin-g and into a room and. including yatransverse passage means having inlet and outlet openings enabling airWithin a room into lwhich said one por-tion projects to circulatethrough said outer sleeve, transverse passage means in said inner sleevehaving inlet and outlet openings enabling air circulating through saidouter sleeve to also circulate Ithrough said inner sleeve, baille meansin said outer sleeve for etecting a tortuous path of the air circulatingtherethrough, portions-of said tortuous path extending longitudinally ofsaid outer sleeve.
